Since 1976, WindTech has manufactured the highest quality American made microphone windscreens on the market. They are available in 25 brilliant colors, and a wide variety of shapes and sizes to fit most popular microphones. Using a proprietary non-heat manufacturing process, our windscreens are constructed from a specially developed hypo-allergenic, open-cell acoustical foam called SonicFoam.The use of SonicFoam permits the free passage of sound energy without altering the microphone's frequency response. While remaining acoustically transparent, our windscreens are engineered to reduce wind velocity which eliminates wind noise, pop noises and breath sounds. For anyone who wants to keep their investment secure, nothing protects an expensive microphone from dust, dampness and physical damage like an external windscreen.
